The women's 4 × 400 metres relay at the 2015 World Championships in Athletics was held at the Beijing National Stadium on 29 and 30 August.

Their ace in the hole was having the top two in the world, prior to the American championships, fail to make the individual event but were available for the relay.

All the other teams ran their season best just to make the finals, Bahamas and Japan set National Records and still failed to qualify.

In the final, it was a reminder of 2008 on this same track as Richards-Ross was out aggressively, making up the stagger on Christine Ohuruogu and when she hit the home stretch, she was out of gas.

While Seren Bundy-Davies carried the British home for bronze, George was overtaken at the line by Russia's Kseniya Aksyonova.
